Which of the following is NOT an external factor affecting businesses?

The correct answer is internal policies because they are fundamentally part of the organization's internal environment rather than an external factor. Internal policies are the guidelines and procedures established by a business to govern its operations, behavior, and practices. These policies are crafted by management to align with the company's mission, objectives, and core values.

In contrast, market forces, supply chain dynamics, and the international and global market are all external factors that influence how a business operates. Market forces involve competition, consumer demand, and economic indicators that affect how much a business can sell and at what price. The supply chain involves external suppliers and logistics that can impact production and delivery processes. The international and global market refers to the broader economic environment, including trade regulations, foreign competition, and global economic trends that can have significant effects on local businesses. Understanding the distinction between internal and external factors is crucial for effective business management and strategic planning.
